Hello Guys!
I tried on the scooter today, it works

Here is a video...but there is a problem, that i sad yesterday...somehow it recieves more than one pulse per revolution, and displays me 10.000 rpm where it is actually 5-6000...so i have to fix it somehow...maybe it can be the solution to make the reciever less sensible, but how?
But a big thank you for this fantastic project!!!
